No download, install or active-user count exists for this self-hosted app, which collects no telemetry, so GitHub stars are the only honest signal available. Stars alone cannot place this higher, because a star reflects attention rather than use, though SillyTavern's real enthusiast and roleplay community is likely larger than stars alone can show.

  28.9k stars, 300+ contributors; no install/usage count published

Feature-rich for its niche, broad backend coverage, image-gen/TTS, extensions, character/roleplay tooling. Specialized toward roleplay rather than general-purpose assistant work; mid-tier on the general chat-UI matrix.
